FIELD OF THE DISCLOSURE

The disclosures made herein relate generally to disposable or recyclable ingredient or beverage bottles and cartons, and more particularly to multi-compartment bottles and beverage cartons providing two or more compartments for storing and segregating ingredients within a common package housing or enclosure.

BACKGROUND

Single compartment beverage bottles and cartons are well known. Carbonated beverages are commonly available in single compartment glass or molded plastic bottles. Single compartment paper carton packages are well known and widely used for packaging of non-carbonated products, for example, milk as well as various fruit juices. While these devices fulfill their intended design objectives and requirements and meet the needs of the consuming public, the aforementioned and commonly available designs do not provided a bottle or carton configured to provide two or more segregated ingredients or beverages within a common container package. In this respect the multi-compartment bottle or carton of the present inventive disclosure deviates substantially from the discussed prior art.

Conventional approaches for packaging beverages have one or more drawbacks. For example—for trips with small children it is advantageous to provide within a single container a choice of multiple flavored beverages to satisfy and pacify children during long trips. Conventional single beverage packages require purchase and transport of two or more beverage packages rather than a single package to fulfill the above multiple beverage objective.

Another limitation of the conventional approaches to beverage packaging is in the life of the product after it is opened. Certain food and beverage products have a limited life after the hermetic seal is broken and the product is exposed to the air. A few examples for illustration purposes include dairy products such as milk, sugar bearing sweetened products, as well as carbonated beverages which will go flat within a short period of time after the seal is broken. Providing two or more sealed compartments within the same package and segregating portions of the product into the compartments extends the useable life of the product after a compartment is opened by maintaining a seal on the unopened compartments until later use.

Therefore, a multi-compartment bottle or carton having two or more sub-compartments for storing and segregating ingredients, food stuffs or beverages, a bottle or carton which packaged for packaging, distribution and retail sale in sizes and forms fitting well with conventional single compartment beverage and food products, one which provides enhanced usable life after the product is purchased and opened, one which provides an extended shelf life with certain types of perishable products by avoiding mixing of the products until after purchase, one which provides benefits to the consumer by offering more than one flavor or type of beverage in a bottle or carton, such a multi-compartment beverage bottle or carton would be useful and novel.

SUMMARY OF THE DISCLOSURE

Accordingly, embodiments of the inventive disclosures made herein comprise a multi-compartment beverage or ingredient bottle or carton designed to segregate two or more beverages or ingredients within a common bottle, carton enclosure while maintaining a hermetic seal between the compartments.

In embodiments of the inventive disclosures made herein, a multi-compartment beverage container comprises a compartmentalized closed container having two or more sub-compartments therein. The sub-compartments are configured for storing and segregating ingredients such as food stuffs or beverages. The container includes a base wall configured to support the container in an upright fashion, say for retail display or storage, a side wall secured along a bottom edge to the peripheral edges of the base so as to form a copy or well, and a top wall having two or more holes therethrough. A neck tube having a threaded end and equipped with a removable cap is sealably mounted over each hole such that for each sub-compartment there is one removable cap providing consumer access to contents stored within the sub-compartment. One or more dividing walls are provided, the dividing walls segregating the container into the two or more sub-compartments as discussed above.

The dividing walls are sealed and secured along the peripheral edges of the dividing walls to the inside surfaces of the side wall, top wall and bottom wall, the structure together with the neck tubes and caps thereon forming two or more sub-compartments having a hermetic seal between sub-compartments and between each sub-compartment and the environment outside the container. The container with the multiple hermetic sealed sub-compartments provides a multi-ingredient container in which beverages or ingredients may be stored for an extended period of time. The caps and neck tubes into each compartment are similar in size and form the threaded necks and thread bottle caps of conventional beverage bottles in common use.

In a first embodiment multi-compartment containers such as described above may be formed from sealably folded and formed paperboard blanks, the paperboard coated with a waterproof plastic, generally polyethylene in present day beverage packaging processes, although the use of, for example, wax coated paper board would serve a similar purpose. Conventional single compartment containers constructed of coated paperboard are commonly available in retail food stores having products such as orange juice, grapefruit juice and similar non-carbonated beverages packed within. The some embodiments of the inventive disclosures herein provide multi-compartment containers for non-carbonated beverages or other ingredients using folded coated paperboard type packaging. As in the case of conventional single compartment containers, the multi-compartment cartons start as coated paper blanks that are fed into a forming and sealing machine. The machine stamps or folds the blank into a carton. The carton seams are sealed by the use of heat and squeezing pressure on the seams without the use of adhesives, as the heated polyethylene bonds the seams strongly without the use of glues or adhesives.

In a second embodiment of the inventive disclosures made herein, a multi-compartment container comprises a compartmentalized closed plastic bottle having two or more sub-compartments therein. The sub-compartments are configured for storing and segregating ingredients such as food stuffs or beverages into a common retail package or container. The container includes a base wall configured to support the container in an upright fashion, say for retail display or storage, a side wall secured along a bottom edge to the peripheral edges of the base so as to form a close wall well, and a top wall having two or more holes therethrough. A neck tube having a threaded end and equipped with a removable cap is sealably mounted over each hole such that for each sub-compartment there is one removable cap providing consumer access to contents stored within the sub-compartment. A primary plastic material used in the manufacture of the multi-compartment plastic beverage container is clear polyethylene terephthalate plastic, which allows the beverage or contents to be viewed through the container by the purchaser or consumer. One or more dividing walls are provided, the dividing walls segregating the container into the two or more sub-compartments as discussed above. The dividing walls are sealed and secured along the peripheral edges of the dividing walls to the inside surfaces of the side wall, top wall and bottom wall, the structure taken together with the tubes and caps thereon forming two or more sub-compartments having a hermetic seal between sub-compartments and between each sub-compartment and the environment outside the container. The container having multiple hermetically sealed sub-compartments providing a multi-ingredient container in which beverages or ingredients may be stored for an extended period of time. The caps and tubes into each compartment are similar in size and form the threaded necks and thread bottle caps of conventional beverage bottles, making the bottle well adapted for beverage packaging for retail and for consumption by the consumer.

In a third embodiment and related embodiments of the inventive disclosures made herein, a multi-compartment container of the second embodiment is modified to have a top wall which is domed in form, the domed form of the top is to strengthen the top wall against the pressure of one or more carbonated beverages contained within sub-compartments of the container. In this embodiment the bottom or base wall may or may not have a concave dome, the dividing wall or wall being secured to the base wall provides additional support to the base wall resisting any buckling tendency due to carbonation pressure.

In the case of paperboard containers, the preferred embodiment of the multi-component paperboard container comprises paperboard having a waterproof polyethylene plastic coating and two sub-compartments, the preferred limit of two sub-compartments primarily for ease of manufacturing, i.e., forming and sealing of the plastic coated paperboard container. It is to be understood however from reading the disclosure herein that the invention is not limited to paperboard containers having two sub-compartments.

In the case of plastic containers, the preferred embodiment of the multi-component container comprises two or three sub-compartment molded plastic containers having domed top walls. It is to be understood however from reading the disclosure herein that the invention is not limited to plastic containers having two or three sub-compartments, but in the contrary to a plastic multi-compartment container having a reasonable number of sub-compartments therein. To help assure the safety of our food, the U.S. Food and Drug Administration (FDA) carefully reviews food and beverage packaging materials, including plastics for beverage bottles, before allowing them on the market. Most convenience-size beverage bottles sold in the United States are made from polyethylene terephthalate (PET). PET has become the material of choice for bottled beverages because it is lightweight and shatter resistant, and PET has been extensively tested for safety by the FDA. Under the Federal Food, Drug and Cosmetic Act, FDA regulates materials and substances used to make plastic packaging as indirect food additives. According to the FDA, indirect food additives are “substances that may come into contact with food as part of packaging or processing equipment, but are not intended to be added directly to food.” Conventional single compartment bottles made with PET are widely used for everything from water and fruit juice to soft drinks and even beer. In view of the established safety records and wide use, preferred embodiments of the plastic multi-component bottle are made from polyethylene terephthalate (PET), although other suitable materials may be substituted as would be known to one skilled in the art.

In certain foodstuffs, it is beneficial to maintain the ingredients separated until use is intended, this providing a longer shelf life. For example, certain dried flavored materials, one example being a sugar based dry drink mix, may be stored for an extended time if the dry ingredients are kept dry. In cases such as this, the liquid portion of the foodstuff, which may just be water and therefore have a long shelf life, may be kept separate from the dry ingredients until the time of use, resulting in a packaged product with an extended shelf life.

It is an objective of the present inventive disclosures to provide a new multiple beverage container which is not anticipated, rendered obvious, suggested, or implied by the known prior art in beverage bottles and cartons.

It is another objective of the present inventive disclosures to provide a new multiple beverage bottle or carton that meets the regulatory requirements of the U.S. Food and Drug Administration, particularly in regard to construction and packaging material and public health and safety.

It is another objective of the present inventive disclosures to provide a new multiple beverage bottle or carton that is reliable in construction and relatively easy to manufacture, resulting in a packaging product that is attractive to the food industry and to consumers due to its innovative design and low packaging product cost.

It is another objective of the present inventive disclosures to provide a new multiple beverage bottle or carton that is easily fillable on automated bottle filling machines and lines.

It is another objective of the present inventive disclosures to provide a new multiple beverage bottle or carton for hermetically storing two or more beverages or ingredients in sub-compartments within a common carton.

It is another objective of the present inventive disclosures to provide a new multiple beverage bottle or carton that is within the fundamental packaging sizes of currently available beverage bottles and cartons, and therefore is adapted to lot packaging, transport, retail display shelving and refrigerated displays without requiring special adaptations to the same.

It is another objective of the present inventive disclosures to provide a new multiple beverage bottle or carton that is convenient and easy for the consumer to use.

It is another objective of the present inventive disclosures to provide a new multiple beverage bottle or carton that saves the consumer time by providing multiple beverages within one single container to more easily satisfy the tastes of the consumer, and, for example, to be particularly beneficial to travelers with children.

It is another objective of the present inventive disclosures to provide a new multiple beverage bottle or carton that may provide a common container for beverages which are naturally mixed together for use, for example rum and a carbonated cola beverage.

These and other objects of the invention made herein will become readily apparent upon further review of the following specification and associated drawings.
